.NET Core API logging output on multiple lines

Question

I'm working with an API running on .NET Core 3.1 and using the framework's default logging which works great for me. I was wondering if I can change the format of the output logs, though, because each individual log output prints 2 lines.

For example, the following line of code:

logger.LogInformation("'{0} {1}'. Status: {2}. Time: {3}ms.",
  context.Request.Method, context.Request.Path, context.Response.StatusCode, responseTime);

Produces the following output:

info: MyApi.Utilities.RequestLoggerMiddleware[0]
'GET /api/users/current'. Status: 200. Time: 8ms.

Is there some way I can get info: MyApi.Utilities.RequestLoggerMiddleware[0] to print on the same line as the message text?

I was able to solve my issue by adding this code after Host.CreateDefaultBuilder(args) in Program.cs and configuring a console logger with the Systemd format:

            .ConfigureLogging(logging =>
            {
                logging.ClearProviders();
                logging.AddConsole(configure =>
                {
                    configure.Format = Microsoft.Extensions.Logging.Console.ConsoleLoggerFormat.Systemd;
                });
            })

The output now looks like this:

<6>MyApi.Utilities.RequestLoggerMiddleware[0] 'GET /api/users/current'. Status: 200. Time: 8ms.
